BEATlNG ENGINE.

SPECIFICATION forming part of Letters Patent No. 717,209, dated December 30, 1902.-

Application filed March 13,1902. Serial No. 98,035. (No model.)

To all whom it may concern.-

. Be it known that I, EDWARD A. JONES, a citizen of the United States, and a resident of Pittsfield, in the county of Berkshire and State of Massachusetts, have invented a new and Improved Beating-Engine, of which the following is a full, clear, and exact descrip- The invention relates to beating-engines, such as shown and described in the application for Letters Patent of the United States, Serial No. 67,587, filed by me July 9, 1901.

The object of the present invention is to provide certain new and useful improvements in beating-engines for insuring a proper circulation of the pulp or stock when the vat is being emptied and dispense entirely with the manually -wielded rakes now usually employed for movin'gthe pulp to the dischargepipe.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out'in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan View of the improvement, part being broken out. Fig. 2 is a longitudinal sectional elevation of the same, parts being shown in elevation. Fig. 3 is an enlarged transverse section of the improvement on the lines 3 3 of Figs. 1 and 4:, and Fig. 4; is a sectional plan View of the same.

The beating-engine shown in the drawings consists, essentially, of the vat A, the beating-drum B, the backfall O, mid-feather D, and discharge-pipe E of usual construction, and under the rear wall of the backfall O is arranged a pressure-chamber F, formed with a jet-opening F for discharging water under pressure into and under the pulp or stock at the bottom of the vat and in the direction in which the pulp or stock is flowing, owing to the action of the beating-drum. Into this pressure-chamber F opens a supply-pipe G, connected at its outer end with a suitable water-supply under pressure. A short pipe G extends through the mid-feather D to connect the pressure-chamber F with a second pressure-chamber H, formed under a portion of the. gusset I at the return side of the midfeather D, andthe said gusset I is provided -With a series of jet-openings 1, formed by making the gusset I in sections 1 spaced apart at their ends and set, preferably, at different angles to each other, as plainly indicated in Fig. 4. The openings I extend in different directions, so that the water passing under pressure through the jetopenings spreads laterally in fan shape and somewhat in downward direction toward the dischargepipe E along the bottom of the vat at the return side thereof and under the pulp to insure ready flowof the pulp down the return side toward the discharge-pipe E.

In the application above referred to I make use of the pressurechamber F, the same as in the present case, to start the pulp around the upper end of the vat; but by having the second jets of water engaging the pulp at the return side of the vat and directing the jets in the manner described it is evident that the pulp is forced down the return side toward the discharge-pipe E without the. use of rakes wielded by an operator.

Having thus described my invention, I claim as new and'desire to secure by Letters Patentl. A beating-engine having a vat provided with a discharge-opening at one end, and a device on the return side of the mid-feather for forcing streams of water into or under the pulp in direction of the discharge-opening of the vat, said device comprising a pressurechamber extending lengthwise of and on the return side of the mid-feather and having a plurality of jet-openings, as set forth.

2. A beating-engine having a device in a vat for forcing a stream of water into or under the pulp, in the direction in which the pulp is flowing, the said device comprising a pressurechamber extending lengthwise of and on the return side of the mid-feather, and having j e't-openings constructed-for directing jets of water laterally in fan shape across the bottom of. the vat and in direction of the discharge end thereof, at the return side thereof, as set forth.

3. A beating-engine having a device in a vat for forcing a stream of water into or under the pulp, in the direction in which the 5 the mid-feather having its discharge-openings arranged to discharge streams of water laterally in fan shape and in direction of the discharge end of the vat, as set forth.

4. A beating-engine having a device in a lo vat for forcing a stream of water into or under the pulp, in the direction in which the pulp is flowing, said device comprising pressure-chambers, one under the rear Wall of the backfall and the other on the return side of I 5 the mid-feather, the chamber under the backfall having its discharge-opening extending from one side of the vat to the mid-feather and the chamber on the side of the midfeather havinga plurality of discharge-openzo ings arranged to discharge streams of water laterally in fan shape and in direction of the discharge end of the vat, and a supply-pipe for supplying thesaid pressure-chambers with a fluid under pressure, as set forth.

5. A beating-engine having a device in a vat for forcing a stream of water into or under the pulp, in the direction in which the pulp is flowing, said device comprising pressure-chambers, one under the rear wallof the backfall and the other on the return side of the mid-feather, the mid-feather pressurechamber having its outer side made in sections, set at angles one to the other and spaced apart at their ends to form jet-openings, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD A. JONES.
